1. The output of an economy is characterized by a Cobb-Douglas production function with constant return to scale and an output elasticity with respect to capital equal to 0.3. Also given are the following parameters: 30% saving rate, 5% depreciation rate, 2% population growth rate, and the technology factor is 2.

a). Find the capital-labour ratio, and also the output, consumption and investment on a per capita basis in the steady state equilibrium.

b). Is a government policy that raises the saving rate to 40% socially desirable? Explain your answer with reference to a comparison of this new steady state equilibrium and the initial steady state equilibrium in a) above.

c). If the initial capital-labour ratio is 30, is the economy operating efficiently in the sense that welfare cannot be improved? Explain concisely. What if the initial capital-labour ratio is 15? Again explain concisely.

The Cobb-Douglas production function is a classic model from economics used to model output as a function of capital and labor. It has the form: f(L,C) = c0Lc1Cc2 where c0, c1, and c2 are constants. The variable L represents the units of input of labor, and the variable C represents the units of input of capital. In this example, assume c0 = 5, c1 = 0.25, and c2 = 0.75. Assume each unit of labor costs $20 and each unit...
